I have a Suntours xcm (spring 80mm) on my hard tail. I drive more frequent and more pretentious. So I consider to upgrade my fork. How can I tell if I need a better one? What can a good air-suspension better than my current?

And what would be a good replacement?



  • less weight
  • more adjustments
  • higher responsiveness

Not sure what you mean by more frequent and more pretentious - naturally, harder trails are better done with better forks (and possibly rear suspension). You may want to rent something better for your usual riding and see if it makes a significant improvement. Make sure the frame and other components are worth it before you do the upgrade - you may find that selling your current bike and then getting something with a better fork is a better proposition once you take into account the cost of the fork and labor for its installation. –  Batman Apr 8 at 15:05

Fork travel is limited by frame. You should look for something about 80mm. You could put 140mm fork, but bike geometry will be uncomfortable. XCM basically is just a spring. Same speed for "down" and "up". If there is local bike club, go to them and ask to try some bike with good fork. Feeling can't be explained :) Gravel feels like tarmac :P

XCM is pretty heavy forк ~2300 grams RockShox Solo Air is less then 1400 grams.
